The present invention relates to a stone box to be used in connection with a sand suction pump and has for its prime object to provide means for separating large stones 6 from the sand to prevent the entrance of said stones into the sandsuction pump. and means whereby the stones may be expeditiously dumped from the box when desired.

A still further very important object of they invention resides. in the provision of a dump stone box of thisinature which is exceedingly simple in its construction; comparatively inexpensive to manufacture, easy to manipulate,-compact and convenient in its arrangement of parts, fairly efiicient and reliable in use and operation, and otherwise well adapted to. the purpose for which it is designed. With the above and numerous other objects in view aswill appear as the description proceeds, the inventionresides in certain novel features of construction, and in the combina- 7 tion and arrangement of parts as will be hereinafter more fully described and claimed.

V a Y Referring to the drawings in detail .it will be seen that the'box comprises afront wall 5, a rear wall6, arounded top 7 and downterminating a distance from the rearwall 6 to provide an opening. A door 19 is hingedly mounted as at 10 ona flange 11 projecting forwardly from the bottom edge of the bot- Figure 4 is a vertical longitudinal section detail section taken substanwardly and rearwardlyinclined bottom 8 tom. 8. A manhole 12 is provided in the top 7 and has a disk closure'l i held against the inner end thereof by bolt"15-and"upward1yj I bowed cross member at 16. The front wall 5, has an opening 17 in the top thereof forming the inlet and an opening 18 is formed iii the' bottom or, the rear wan 6 to providethe out let. A shelf or chute 19 is mounted'on the inside of the front wall 5 belowthe inlet and inclines downwardly and; rearwar'dly. A grate 20ismounted onthe rear wall6 adja- 60 cent the upper endthereofand inclines down I wardly and forwardly and is raisedbyacross lione-mber 21 betweenthe side walls 22 of the ox.

The box is supported on suitable frame work 23. Rises 24 on the framework 'termi-i. nate above the box and support bearings 25 in which is journaled a shaft 26 liaving cranks 27 onthepe'n ds thereof. Links 28 are connected with these cranks 27 andextend down-i '1 wardly and have a pivotal connection as at30 i with anintermediate portion of the. door 9.. A handle 31 is fixed to an intermediate por tion of the shaft 26 and rests on a ledge on'the top 7 when the cranks 27 are inclined 7,5 upwardly and forwardly as is illustrated in full lines in Figureit. I Nowby swinging the handle upwardly the cranks maybe swung around to; a "depending position thereby al f lowing the vdoor to. swing down to an open position.- A grate is; denoted generally by the 2 letter Gand is rockably mountedat 33 ad jacent the front wallfibetweenthe side walls 7 22 andabovethe upper end of the bottoin 8 and normally inclines downwardly and rearwardly and the rear end is supported by arms 34 pivoted to the grate G as at35 andipivoted on the door 9 as at 36. ,It. will therefore be seen that whenthe door '9 is swungtoan open position the grate G takes the dotted [line position shown in Figure/i allowing stones and the like to roll thereoif through i the openings.

This Gimme w ens-of iparallelic'oextensive bars .38 held set rela 5 tionship by bolts 39 with spacersAOthereon. p r

some large stones, larger than is wanted in the pump, comes into the sand box through v the inlet and enters the upper portion of the stone box with the grate G in a closed or raised position. The grate is of such a size sufficient to permit only gravel and stones of a desired size to drop through and this gravel drops: into the bottom of the box and goes out through the outlet 18. The-stones that cannot pass through the grate. remain on the upper portion of the stone box and when this becomes filled with; stones,. by. means of the handle 31, the bottom of the stone box is opened and the grate lowered allowing the stones. to rolloif .of the grate out of theboxi- When. the" stories have passed through-the bottom: the door has been'closed and the pump is put" in operation. ,The

manhole coverin the top is removable so that the operator ofthe pump can takelt off and.

help pushthestones out'of the box'i'f this is necessary;

,The advantage of this box over those of other stone hjoxes' is that this stone box has a'bottomthat'ca'n beopened' bymeans ofthehandle 31' and the. stones can bei'taken out thro'ugh'thel'bottom}of'thebox;

Iti's thought that'the" construction, op-

.. oration and utility and advantages of this in'= vention wil'l now be quite apparent to those skilled in this art without a .more detailed descriptiomthereofa V The presentembodiment ofithe invention .has been described in considerable detail scription.'
